BAR-US Anchor-Nut® is an easy to install and structurally improved rebar anchorage system that replaces hooked rebars in concrete based on the principles of the Shear Cone Theory used by ACI-355.

Traditionally, anchorage of rebars within a concrete section is done by creating long hooked ends on the rebar. BAR-US Anchor-Nut® creates an anchorage in the concrete, transmitting the bond force from the rebar to the concrete by a combination of head-bearing and development length. Anchor-Nut® can simplify scheduling and bar placement as well as reduce congestion and air pockets in the concrete.

By using headed mechanical end anchors, hook bars are eliminated and rebar congestion is minimized resulting in improved space for pouring and vibrating, thereby enhancing concrete consolidation, lowering concrete placement costs, and improving in-place concrete quality. When using reinforcing bars with headed ends, the load reaction between the rebar and concrete is evenly distributed.

Custom designed for use on #4 (12 mm) to #8 (57 mm) reinforcing bars, BAR-US Anchor-Nut® creates a full length splice with the mode of failure being bar break. BAR-US Anchor-Nut® is designed to exceed the strength requirements of ACI 318, Section 12.6 or 100% of the Specified Yield Strength of Grade 60 bar.
